Sprains 
By far the most common sports related injuries would be sprains, but what is a sprain? Sprains are stretches or tears of ligaments which are connective tissue that connect one bone with another. This type of injury can vary in severity. 

Strain 
A strain is a twist, pull, or tear of a muscle or tendon. Although common in contact sports, this type of injury can also be seen in athletes who perform repetitive motions such as tennis players or golfers. Similarly to sprains, these types of injuries can range from a minor strain to a complete tear of the muscle/tendon.

Bone Fracture 
A fracture is a break in the bone from either a quick one time injury (acute fracture), or from repeated stress (stress fracture). Acute fractures are more common in accidents such as car crashes or falls while stress fractures are more common in sports where there is repetitive impact such as running or jumping. 

Dislocation 
A dislocated joint is when the two bones involved in the joint become separated. This type of injury can be seen in contact sports such as football and hockey, as well as high-impact sports such as soccer and basketball. 

Tendinitis 
Tendinitis is the inflammation of a tendon, the connective tissue that connects muscles to bones. This injury is mainly seen in the shoulders, elbows, wrists, hip, knee, or ankles. Tendinitis is usually the result of performing the same motion over and over again. Just like strains, this type of injury is more common in tennis players and golfers.
